The Lion Sword is the fifth main weapon in Warrior Within. This sword gives the Prince the ability to store up energy, and then unleash a more devestating attack.
It was given to the Prince by Kaileena, and is the sword in which he fights her with. Kaileena cursed this sword in order to prevent the Prince from activating the Towers. Ultimately, the sword is broken after the Prince's battle with Kaileena, forcing him to seek out a new weapon (the Scorpion Sword).
